MACHINE FOR ENAME LING CLAY ARTICLES.

SPECIFICATION forming part of Letters Patent No. 720,594, dated February 17, 1903.

Application filed September 23, 1902- Serial No. 'l24,528. (No model.) i

,to provide a machine calculated to thoroughly cover with slip -i. e., enamel or glaze-the face or faces of clay articles intended to be exposed in walls or other places in such manner that waste of the slip is precluded and the necessity of a'workman placing his hands in the slip orgetting some of the same on his hands is obviated.

Another object of the invention is to provide' a machine calculated to expeditiously remove enamel or glaze from those surfaces of anenameled brick or other article which are not intended to be enameled and this in such manner that the necessity of a workman inhaling enamel-dust, as when the superfluous enamel is removed with a hand-brush, is

Referring by letter to the eaid drawings,

and more particularly to Figs. 1 to 3, wherein is shown the means for applying slip to the clay articles, A is a frame having antifric tionrier arranged on pulleys b in the frame and having its upper stretch arranged on and supported by the rollers a; O, a tightener which I prefer to use for taking up undue slack of and keeping the carrier properly taut; D, a tank supported by a suitable frame '0 in a plane above the upper stretch of the carrier and designed to contain the liquid slip or other substance to be applied to the clay articles; E, an arm connected in a hinged manner. to the frame 0 and arranged to swing transversely above the upper stretch of carrier 13 s5 rollers a at its upper side; B, an endless car- F, a metallic or other suitable nozzle attached to the arm E and connected through the medium of a flexible tube 01 with the tank or slipreceptacleD; G, a metallic or other suitable nozzle fixed to the nozzle F, preferably with its discharge disposed at right angles or approximate right angles to that of said nozzle F, and connected through the medium of a flexible tube @With a pipe f, designed to be connected with a source of steam, compressed air, or other fluid-pressure supply (not shown) or with an overhead source of water-supply, (also not shown H, a swinging arm'comprlsing, by preference, an upper section g, pivoted on the-frame c and having a plurality of apertures h, a lower section 1,, and a bolt connecting the said sections; I, an eccentric designed to be rotated through any suitable drivingv connection; J ,--an eccentric strap containing the eccentric I andhaving an arm is, connected tothe swinging arm H, prefer-. ably through the medium of the bolt 7,'and K the arm r 9 a strap or bar interposed between and con-" In the practical operation of the'portion of my improved machine thus far descri-bedin. detail the carrier Band the eccentric I are driven by any suitable means, and slip and fluid-pressure or aproper head of water are supplied to the nozzleF and the nozzle G, re-

spectively. The bricks, tiles, orother articles'to'be enameled are placed on the" upper stretch of the carrier, and as they pass bee neath the nozzles F G said nozzles, swinging transversely to and fro, will spray slip-.on their upper sides or faces and properly cover the same and this without considerable waste of slip and also without the necessity of the operators hands coming in direct contact with the slip, which in many cases contains as components carbonate of lead, oxid of lead, minium or red lead, and other more or less poisonous substances deleterious to the health of the operator. Motion is transmitted from the cam Ito the arm E through the strap J and its arm 70, the arm H, and the strap or bar K, and it will be seen that by increasing and diminishing the length of the arm H the traverse of the arm E and nozzles F G'may be increased and diminished-i. e., regulated to adapt the nozzles to properly spray and cover'with slip the upper sides of clay articles of various lengths. After the uppersides or faces of the clay articles are covered with slip said articles are carried forwardly on the carrier until they reach points opposite the shelves Z of that portion of the machine designed to remove superfluous enamel or glaze from the articles, when they are taken-offthe carrier by attendants and held on the shelves in the manner hereinafter described. In the preferred embodiment of my invention the portion of the machine designed to remove enamel from those surfaces of clay articles not intended to be enameled comprises a casing L, Figs. 4 and 5, disposed at right angles to the carrier B-and having the shelves Zon its side walls and alsohaving openings m in saidside walls immediately above the shelves, a transverse shaftn, journaled in suitable hearings in the casing, disks p, fixed on said shaft and having wire orother suitable brushes g on their outer sides, and a pulley 'r, fixed on the shaft between the disks p and designed for the engagement of a belt 8, which extends through the top of the casing.

When the bricks or other clay articles are held on the shelves 1, so as to present their surfaces which are not intended to be enan1-.

eled to the brushingor abrasive action of the ing, and the liability of the attendants breathing such dust will be reduced to a minim um.

. of the articles.

It will further be observed that when the bricks, tiles, or other articles are "enameled before burning'and the superfluous enamel is removed by the means described a finished appearance will be given to the articles, and at the same time the cost of producing the same is materially reduced.

The means which I have shown and described for efiecting the application of slip to bricks and other clay articles is adapted to cover with slip the upper sides or faces only 7 This in some cases willnot be sufiicient, as. it is sometimes required to nozzles, the said extra nozzles being arranged;

in an approximately horizontal position and being connected through comparatively long tubes with the tank D and the pipef.

In Fig. 6 of the drawings I have illustrated a modified construction which comprises all of the elements of the construction shown in Fig. 2 and in addition a pair of horizontal or approximately horizontal nozzles F G, connected by flexible tubes with the tank D and the pipe f, respectively, a vertically-rocking support E, to which the nozzles are attached, an arm H, fixed and disposed at an angle to the arm H, a pitman a interposed between the rocking support and the arm H and connected to thelatter in an adjustable manner,so that the throw of the nozzles F G may be regulated, and a shield H connected to the opposite side of the frame A with reference to the nozzles F G and terminating'at its lower end in a gutter H The operation of this modified construction is similar to that of the construction shown in Fig. 2, with the exception that slip is applied to the upper sides or faces of the bricks or other clay articles and also to the heads or ends thereof. The nozzles F G. are oscillated in avertical plane through the medium of the. mechanism described with a view of' assuring the proper covering with slip of the heads or ends of the bricks or other articles on the carrier B. 'The shield H has for its purpose to prevent scattering of the slip discharged by the nozzles F 'and G.

While I have described the pipe f as being designed to be connected with a source of steam, compressed air, or other fluid-pressure supply or with an overhead sourceof watersupply, I prefer to connect said pipe with a source of compressed-air supply and to use compressed, air to assist in the application of the slip.

I have entered into a of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of'my invention in ordercarrying the said slip-applying means, an

eccentric, and an operating connection intermediate of said eccentric and oscillating devlce, comprising means whereby the throw or loo detailed description traverse of the swinging device may be increased or diminished.

In a machine of the character described, a work-support, slip-applying means movable above the support, slip applying means movable at the side of the support, a shield arranged at the opposite side of the support with reference to the latter slipapplying means, an eccentric, and operating connections between the eccentric and the two slip-applying means.

3. In a machine of the character described, a work-support, slip-applying means mo'vable above the support, slipapplying? means movable at the side of the support, a shield arranged at the opposite side of the support with reference to the latter "slipapplying means, and terminating at its lower end in a gutter, an eccentric, and operating connections between the eccentric and'the two slip-applying means.
